In order to explore the infiltration performance of Xiamen sponge city reconstruction completed area, the soil saturated hydraulic conductivity of two sponge roads and a sponge plot was measured by Guelph infiltrometer. The differences of soil saturated hydraulic conductivity measured by 5 cm single-head, 10 cm single head, single-head mean and double-head method were compared and analyzed. The soil saturated hydraulic conductivity in spongy and non-spongy areas was also compared. The results show that the infiltration performance of Xinshun Road greenbelt with ecological porous fibre cotton is the best, followed by Xinjing Road greenbelt with general transfer grass-planting trench, while the infiltration performance of B13 green space in Yangtang residential area with waterproof roof and underground parking lot is the worst. The results of different water head measurements show that the standard deviation of soil saturated hydraulic conductivity calculated by 5cm single-head method is the smallest, and that of double-head method is the largest. It is recommended that 5cm single-head method be used to calculate soil saturated hydraulic conductivity in Xiamen for soil infiltration test.
